To all whom it may concern.-

Be it known that we, JOHN A. BROWNING and THOMAS M. ST. JOHN, citizensof the United States, residing in New York city, county and State of NewYork, have invented certain new and useful Improvements inCopying-Machines, of which the following is a specification.

The object of our invention is to supply a means for the readyproduction of a number of copies of drawings and written matter by adry-copying process.

Our invention contemplates making the copies on a continuous strip ofpaper or on separate sheets of paper, and the machine is designed to bereadily adjusted to accomplish these ends.

The construction and operation of the machine will be understood byreference had to the accompanying drawings, forming a part of thespecification, in which Figure 1 is a side elevation of our improvedcopyinganachine adjusted for printing on a strip of paper. Fig. 2 is acentral longitudinal section of the same. Fig. 3 is a view of theabsorbent-roller-controlling device detached. Fig. 4 is a longitudinalsection of the machine adjusted for printing on separate sheets ofpaper. Fig. 5 is a front elevation of the same, and Fig. 6 shows one endof the clamping device for holding the absorbent covering on its roller.

The two main side frames to and a areconnected together by the tie-rodsa a and are secured to the base a At the front ends of these frames isjournaled the pressureroller 1), and at their rear ends are providedopen bearings for the shaft 0, which carries the roll of paper 0, andagainst this shaft springs c bear and act as brakes to prevent racing ofthe roll of paper when it is being printed upon.

On boxes concentric with the axis of the roller Z) are fitted theswinging frames cl cl, which carry the other rollers of the machine, andthe plate 6 (said plate being securely fastened to the frames by screws)acts as a brace to bind the frames together and also performs thefunctions of a knife, over the edge of which the strip of paper may becutinto sheets after being printed upon, and this edge may be serratedto facilitate this work.

To look the swinging frame in its two 0perative positions, the bolts f fare fitted to rotate in holes in the side frames CL a, their innercylindrical portions being cut away, as shown in Fig. 2, to allow thecurvilinear parts 61 of the frames .rl cl to pass over them while saidframes are being shifted, and they act as stops to determine the twopositions of the frames by the outer edges of the recesses d and 61coming in contact with them. These recesses are shaped to receive thebolts ff when they are rotated by their finger-pieces f f to firmly lockthe frame. Figs. 5 and 6 show the frames (2 d locked in their upperposition.

The paper-receiving roller g has bearings in the frames d d, is providedwith a crankhandle 9 and with a paper-gripping device consisting of arod 9 and end plates g fastened to the ends of the rod and pivoted tothe ends of the rollers in such manner as to permit the rod to pass intoa longitudinal groove formedin the roller, so as to carry with it theend of the paper and thereby clamp it to the roller.

Between the rollers 12 and g is located the stripping guide-roller h.This roller h we have found essential to cause the paper to leave theabsorbent roller freely, for its adhesiveness is such that the paper isliable to become creased when wound on the roller 9 directly from theabsorbent roller. The absorbent surface of the impression-roller t'consists of a gelatinous or other material j suitable to absorb the inkof the drawing or writing to be copied, fixed on afabrio backingj, andto enable this absorbent surface to be readily applied to and removedfrom the cylon the shafts 2' 2' These catches Z Z, when the coveringj jis being applied, are moved over with their ends Z in line with thegroove 11. One end of one of the rods is placed under the end of one ofthe catches, so asto project a little beyond the catch. This end of thefabric and rod are then placed in the groove and slid lengthwise untilthe other end of the rod passes under the end of the othercatch. Thecovering j j is now wrapped around the roller '1', said roller beingheld away from the pressure-roller h during this operation, ashereinafter described, and the other end of the fabric and its rod areinserted in the groove and under the ends of the catches. over, theircam or inclined surfaces acting on the ends of the rods 76 7t to drawthe roc s toward the center of the roller, thereby causing the coveringto hug the roller closely. To prevent the rods 7c 7; working outendwise, the catches are provided with the flanges Z Z and to assist ininoving the catches over to draw on the rods 76 7c the guide-brackets mm, fastened on the ends of the rollers t, are provided, said piecesbeing so shaped as to overlap flanges Z Z and thus hold the outer partsof the catches against the ends of the roller 2'. To cause the roller tto bear with a yielding pressure against the pressure-roller Z) and tohold it away when required the following device is employed at each sideof the machine. A plate a is held against the frame by a screw a andreceives the end of the shaft Said shaft also plays in the slot (1,which has its opening near where the screw n is located, as clearlyshown at Fig. 3. The plate at has a curve-shaped slot which works on thescrew '17. and which has a re-entrant notch 41 The spring 0 is attachedto plate a and the frame and draws the rollert' toward the roller 1).Now to withdraw and hold the roller away from the roller 1) the plates11 n are moved back until the re-entrant notches n a catch over thescrews 11 n, and when it is desired to entirely remove the roller '2'.for the purpose of replacing itby another of a different size the screwsn n are taken out and the plates not slipped off the ends of the shafts1' e which allows the shafts to slide out of the slots d To operate froma roll of paper the machine is set as shown at Figs. 1 and 2, the papera placed on the shaft 0, around the pressureroller b, the guide-roller72, and clamped to the roller g, upon which it is wound. The roller 1',with its absorbent surface carrying the device or matter to be printed,bears against the paper as it passes over the roller Z) and imprints itas fast as it can be conveniently wound on the roller g. The paper 0 isshown as passing under the tie-rods a a This is not necessary. IVhen asmall roll is used, it can pass directly to the roller 1); but if aslarge a roll as can be placed in the machine be used then it may beconvenient to pass the paper under the rod a After the desired number ofimpressions have been run off, the paper from the roller g, after beingseparated from the main roll, is drawn over the knife 0, as shown at 0and by means of its edge out or torn into sheets. In operating withseparate sheets, with the swinging frame and its attendant parts set inThe catches are now moved the position shown at Figs. at and 5, atable 1) is used, upon which the sheets are placed to be fed to themachine. This table is provided with hooked brackets 19 p at one end,which set over the projections a or, extendin g upwardly from the frontend of the frames to a, said brackets having side lugs 19 13 which restagainst the sides of the frames a a to prevent lateral movement of thetable thereon. The roller 1' is prepared for this work by placing astrip of paper or other suitable material (1 on the absorbent surfaceextending over the slot 1" or where the spaces at the top and bottom ofthe sheets to be printed will come. Gelatinous material, if used, hassufficient adhesiveness, especially if slightly moistened, to hold thispaper q in place. In starting, the roller is set with this piece ofpaper (1 adjacent to roller 1), the end of the first sheet r to beprinted is started between the rollers, and the roller i is turned untilthis end of the sheet is at top, as shown. The end of paper 9 is, byreason of the paperguard q, free and easily grasped by the fingers,which would not be the case if this guard were omitted. The sheet is nowpulled, stripped from the roller, and the roller rotated until the guard1 again comes in position for the end of the next sheet of paper to befed against it. Then upon continuing the pull on the first sheet untilit is clear of the roller the free end of the next sheet is in positionto be grasped by the hand, which is pulled off the roller, as was thefirst sheet, and another sheet fed, as before, and so on, the work beingaccomplished as quickly as the sheets can be fed to the roller andpulled off.

The table 19 is of a width to lie in the bottom of the machine betweenthe frame a a when not in use, and is so shown in Figs. 1 and 2.
